Protection mechanism for connectors
A protection mechanism in accordance with a preferred embodiment of the present invention includes a bracket for being secured to a rear portion of a computer chassis, and first and second covers respectively pivotally attached to the bracket. Adjacent sides of the first and second covers each form a lug. The lug of the first cover abuts against the lug of the second cover so as to prevent the second cover from rotating.

No. 11/156,518, filed on Jun. 20, 2005, and entitled “PROTECTION DEVICE FOR CONNECTORS”; and the copending U.S. patent application Ser. No. 11/306,454, filed on the same date and having a same title with the present application, which are assigned to the same assignee as this patent application.
FIELD OF THE INVENTIONThe present invention relates to a protection mechanism for connectors connected to a computer.
DESCRIPTION OF RELATED ARTDevelopments in networks and a great diversity of computer performances have resulted in more and more input/output interfaces disposed at a computer chassis. A typical computer chassis includes a plurality of connectors connected with cables. These cables include a power cable, a signal cable connecting a monitor, a mouse cable, a keyboard cable, a network cable, a microphone cord, and an earphone cord, etc. These cables are often in a mess at a rear panel of a computer, thereby resulting inconvenient during assembling or disassembling the computer.
In addition, the connectors at the rear panel are exposed in the air. Dust is often accumulated thereby affecting signal transfer. Furthermore, the connectors connected to the rear panel of the computer chassis are susceptible to being broken of or inadvertently disconnected because the connectors typically extend outwardly from the rear panel a substantial distance.
What is desired, therefore, is to provide a protection mechanism for protecting connectors of a computer from contamination or being damaged.
SUMMARY OF INVENTIONIn one preferred embodiment, a protection mechanism includes a bracket for being secured to a rear portion of a computer chassis, and first and second covers respectively pivotally attached to the bracket. Adjacent sides of the first and second covers each form a lug. The lug of the first cover abuts against the lug of the second cover so as to prevent the second cover from rotating.
The protection mechanism further includes a lock to lock the first cover to the bracket.
When the second cover is closed, a free end of the second cover abuts against a side of a side panel of the computer chassis to prevent the side panel from withdrawal.
In this preferred embodiment, the side panel can be disassembled only when the second cover is opened, and the second cover can be opened only when the first cover is opened. Thus, only one lock can control the two covers and the side panel.
Other advantages and novel features will become more apparent from the following detailed description of preferred embodiments when taken in conjunction with the accompanying drawings, in which:
Referring to
The bracket 30 includes a U-shaped outer frame 31, and an inner frame 33. The outer frame 31 has a cutout 32 corresponding to the side panel 14 of the computer chassis 10. The outer frame 31 includes two arm portions 311, and a crossbeam 35 perpendicularly connecting the arm portions 311. The crossbeam 35 divides the outer frame 31 into two regions, one larger than the other. The first cover 40 is pivotally accommodated in the larger region, and the second cover 50 is pivotally accommodated in the smaller region. Pivot ends of the first and second covers 40, 50 are in the vicinity of the crossbeam 35. Three cutouts 352 are defined in an inner side of the crossbeam 35.
The inner frame 33 is recessedly formed between the arm portions 311 of the outer frame 31 for reinforcing the bracket 30. Four threaded holes 331 are defined in four corners of the inner frame 33, respectively. The bracket 30 is thereby secured to the rear panel 12 of the computer chassis 10 via screws. The inner frame 33 defines a plurality of openings in order not to shield the input/output interfaces. A locking portion 332 is formed at the inner frame 33 besides one of the openings.
Referring also to
The second cover 50 is substantially arc-shaped, and defines a plurality of ventilation holes 51. Three lugs 52 protrude outwardly from the pivot end of the second cover 50. Two protuberances 53 are formed at each lug 52. Two opposite sides of the end away from the pivot end of the second cover 50 each form a resilient tab 54. A knob 55 protrudes outwardly from the resilient tab 54.
Referring also to
The first cover 40 defines a lock hole 49 for accommodating the lock 70 or other locking means therein. The lock 70 as shown in
When opening the second cover 50 is needed, the first cover 40 must be opened firstly. The lock 70 is screwed with a key to release the first cover 40. The first cover 40 is rotated outwardly so that the lugs 47 leave the lugs 52, the second cover 50 is thereby capable of being rotated outwardly. The side panel 14 is then capable of being disassembled from the chassis 10 after the second cover 50 is rotated outwardly.
In this preferred embodiment, the second cover 50 is designed to be a separate part of the first cover 40, and rotated in a reverse direction of that of the first cover 40. This leaves the side panel 14 a withdrawal distance. If there is an integrated cover rotated at the side of the side panel 14, an undesired distance must be designed between the side panel and the cover for withdrawal of the side panel 14.
The second cover 50 can be opened only when the first cover 40 is opened. The side panel 14 can be disassembled only when the second cover 50 is opened. Thus, only one lock can control the two covers 40, 50 and the side panel 14.
It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being a preferred or exemplary embodiment.
Claims
1. A computer enclosure comprising:
- a side panel movably attached to a side of a computer chassis, and only detachable from the side along a direction perpendicularly toward a rear side of the computer chassis;
- a bracket arranged to a rear portion of the chassis, one side of the bracket defines a cutout for withdrawal of the side panel;
- a first cover pivotably attached to the bracket around a first axis, a free end of the first cover lockable to the bracket, a lug extending from the first cover, the lug and the free end of the first cover located at two opposite sides of the first axis; and
- a second cover pivotably attached to the bracket around a second axis, the first and second axes being adjacent to each other and parallel with a rear end of the side panel, a free end of the second cover blocking the rear end of the side panel from rearward movement when the second cover is closed, a lug extending from the second cover, the lug and the free end of the second cover located at two opposite sides of the second axis;
- wherein the lug of the second cover is placed on an outer side of the lug of the first cover, such that the first cover must be opened first to open the second cover.
2. The computer enclosure as claimed in claim 1, wherein the bracket comprises two opposite arm portions, two opposite ends of the first axis respectively engage with the two arm portions, and two opposite ends of the second axis respectively engage with the two arm portions.
